⚡ Performance Guide
Comprehensive guide to optimizing HyperFabric Interconnect performance for maximum throughput and minimum latency.
Performance Overview
HyperFabric Interconnect is designed for ultra-high performance computing scenarios where every nanosecond matters. This guide covers optimization strategies, benchmarking, and troubleshooting techniques.
Key Performance Metrics
| Metric | Target Range | Best Practices |
|---|---|---|
| Latency | 50ns - 1ms | Use quantum/photonic hardware, optimize routing |
| Bandwidth | 10 Gbps - 1 Tbps | Enable compression, use zero-copy buffers |
| Throughput | 95%+ utilization | Load balancing, parallel transfers |
| Packet Loss | < 0.001% | Fault tolerance, redundant paths |
| Jitter | < 1% of latency | Consistent hardware, QoS prioritization |
Hardware Optimization
